Phenomenological characterization of sequential dual-curing of off-stoichiometric "thiol-epoxy" systems: Towards applicability [PDF]
, 2017 An extensive characterization of a sequential dual-curing system based on off-stoichiometric “thiol-epoxy” mixtures was carried out using thiol compounds of different functionality.

An explanation for the interaction mechanism of an anionic polymeric additive on yeast flocculent cells [PDF]
Biotechnology Letters, 1994 Magna Floc LT25 is a high molecular weight anionic polymer that has been described as increasing reaction rates inside flocs of yeast cells. However, no clear indication has been given on how this anionic polymer interacts with flocculent cells. Flocculation experiments made with a strain ofSaccharomyces cerevisiae corroborate that it bridges calcium ...

Curing of off-stoichiometric amine–epoxy thermosets [PDF]
, 2018 The kinetics of the epoxy–amine polycondensation and the epoxy homopolymerization in off-stoichiometric epoxy/amine formulations with excess of epoxy groups, and in the presence of an anionic initiator have been investigated.

Combinatorial biomaterials discovery strategy to identify new macromolecular cryoprotectants [PDF]
, 2020 Cryoprotective agents (CPAs) are typically solvents or small molecules, but there is a need for innovative CPAs to reduce toxicity and increase cell yield, for the banking and transport of cells.

Ruthenium-Based Heterocyclic Carbene-Coordinated Olefin Metathesis Catalysts [PDF]
, 2010 The fascinating story of olefin (or alkene) metathesis (eq 1) began almost five decades ago, when Anderson and Merckling reported the first carbon-carbon double-bond rearrangement reaction in the titanium-catalyzed polymerization of norbornene.

Sequential curing of thiol-acetoacetate-acrylate thermosets by latent Michael addition reactions [PDF]
, 2017 Thiol-acetoacetate-acrylate ternary dual-curing thermosets were prepared by a sequential process consisting of thiol-Michael addition to acrylates at room temperature followed by Michael addition of acetoacetates to acrylates at moderately elevated ...

Journal of Membrane Science, 2019 Abstract Stable, non-hydrolysable, hydroxide-conducting polymers are of interest for electrochemical devices such as fuel cells, electrolyzers and flow-batteries. In this study, a series of tetrablock copolymers containing an all-hydrocarbon backbone were synthesized.

Polymer Chemistry, 2022 Herein we propose the preparation of crosslinked polymers from off-stoichiometric oxa-Michael formulations proceeding via a self-limiting base catalyzed reaction between difunctional Michael acceptors and substoichiometric amounts of diols followed by anionic polymerization of the remaining vinyl groups.

Thermal Stability Evaluation of Polystyrene-Mg/Zn/Al LDH Nanocomposites
Nanomaterials, 2019 A series of samples of Mg/Zn/Al LDHs (layered double hydroxides) materials was prepared by the co-precipitation and urea hydrolysis methods. They were modified with organic surfactants (acrylate and oleate anions) and characterized by X-ray diffraction ...
